曲率属性在微幅度构造识别中的应用
|
摘要
随着油田勘探开发的不断深入,微幅度构造油气藏越来越受到重视。常规识别微幅度构造方法是内插密间距等值线编制精细构造图,但构造成图时人为因素影响极大,降低了微幅度构造识别的可靠性。利用曲率属性开展微幅度构造定量识别,取得较好效果。实际应用成果表明:最大曲率属性在微幅度"构造脊"的识别中具有独特优势,而最正曲率属性可以很好地识别微幅度构造的范围。曲率属性为微幅度构造识别提供了一种有效途径。
With the continuous deepening of the oilfield exploration and development,more and more attention has been paid to the micro-amplitude-structure petroleum reservoirs. The conventional identifying method is to compile a fine structural map by means of the interpolated dense-interval contour line,but the human factor has a great influence on the construction of the structural graph,thus the reliability of the micro-amplitude structure identification is reduced. With the help of the curvature attribute,the quantitative recognition of the micro-amplitude structure was conducted and much better achievements have been obtained. The practical application results show that the maximal curvature attribute has a unique advantage in the recognition of the micro-amplitude "tectonic ridge",besides the most-positive curvature attribute can well identify the scope of the micro-amplitude structure. The curvature attribute has provided a kind of the effective approach to identify the micro-amplitude structure.
